TRINALIN vs X-TROZINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
TRINALIN is a combination of azatadine, a first-generation antihistamine that antagonizes histamine H1 receptors, and pseudoephedrine, a sympathomimetic amine that stimulates alpha-adrenergic receptors, causing vasoconstriction and reducing nasal congestion.
X-TROZINE acts as a selective serotonin reuptake inhibitor (SSRI) by binding to the serotonin transporter (SERT) and blocking reuptake of serotonin, thereby increasing serotonergic neurotransmission.
One tablet (azatadine 1 mg/pseudoephedrine 120 mg) orally every 12 hours. Not to exceed 2 tablets in 24 hours.
100 mg orally twice daily

Terminal elimination half-life approximately 20-30 hours; clinical context: allows twice-daily dosing for sustained decongestant effect
Terminal elimination half-life is 12-15 hours in healthy adults; prolonged to 24-36 hours in severe renal impairment (CrCl <30 mL/min), requiring dose adjustment.
Renal: 70-80% as unchanged drug and metabolites; biliary/fecal: 20-30%
Renal excretion accounts for 60-70% of total clearance, predominantly as unchanged drug. Biliary/fecal elimination constitutes 20-30% via P-glycoprotein-mediated transport. Minor metabolism (<10%) via CYP3A4.
